Definitions

  • the present invention is directed to the technical field of electrical cable manufacturing in general and relates to a detorsion stranding machine for making bundles of threadlike elements in particular optical fibres .
  • the general concept of the invention consists in using a detorsion stranding machine which preferably operates vertically and where the fibre stranding centre is eccentric with respect to the machine centre . More in detail , the fibre stranding centre is offset , with respect to the turntable rotation axis passing through the machine centre , by a distance substantially equal to the diameter of the filled unwinding coil .
  • the machine according to the invention consists essentially of a horizontal turntable 1 whereon a plurality of detorsion decoilers are mounted , each comprising preferably a pair of coils 2 fixed on fibre decoiler shafts having one end pivotally mounted on an antitorsional arm which has an end pivotally mounted on the turntable 1 and extends downwards perpendicularly thereto .
  • Each decoiler allows the unwinding of two fibres 4 for each antitorsional arm 3 and is equipped with a coil braking mechanical system implemented by means of special harmonic rods with pads (not shown) , each acting on the respective fibre decoiler shaft and being micrometrically adjusted by means of a special screw having a braking sensibility of ⁇ 2g in the range 5 ⁇ 50g (values used for optical fibre stranding) .
  • Turntable 1 is rotated in a conventional manner about its axis by motor 12 which drives , through toothed belt 17 , gear wheel 21 keyed on the same shaft of another gear wheel 9 rigidly fixed to turntable 1 .
  • Motor 12 which is controlled as to both speed and leading and trailing ramps , rotates via the toothed belt 17 and the pair of gears 21 and 9 , cause rotation of the turntable 1 which in turn transmits the detorsion movement , by means of the driving belt 11 , to double decoilers .
  • the whole is controlled in such a way that each antitorsional arm 3 is rotated a full turn for each turn of the turntable 1 , so that the coils mounted thereon (3) still maintain the same orientation thus avoiding the fibre torsion .
  • the revolving arms 6 and the adjustable rest 8 , the fibre guide 5 and the stranding die 7 define a right circular cone whose axis 0'-0 is parallel to 0-0 axis and spaced therefrom by a distance "d" substantially equal to the filled coil diameter .
